Application filed dctober' 30, 1923, Serial No. 671,818. RenewedDecember 13, 1926.

This invention relates to water radiators for the cooling'systems of internal combustion engines and has particular reference to an improved filling spout and closure cap therefor particularly adapted for use uponsuch radiators.

It is well known that for many reasons an internal combustion engine such as is commonly used in motor vehicles, will over- 1 heat or become excessively hot so as to'cause boiling of the water in the cooling system of said engine, Whenvthis boiling of the water takes place, considerable danger is presented, such as bursting of the closure cap of the filling spout of the radiator and its forcible projection fromjthe spout, and, should the cap of thefilling spout be removed at this time, the person removing the same is subject to being severely burned by the escaping steam and boiling water.

The primary object of the present invention, therefore, is to provide a filling spout and closure captherefor, through which the use of which the radiator will be sui'ficiently vented to permit escape of steam therefrom, so that when the cap is removed from the filling spout, the person removing the same will not be subject to being burnt by the boiling water, and whereby destruction of the cap is eflectively prevented.

Another object of the invention is to pr ovide means for regulating th'eescape of heat from the radiator or entrance of cold air thereinto, so that the device will not inter 3 fere with the operation'of the engine during cold weather. j v

Other objects will appear asthe nature of the invention is better understood, and the same consists in the novel form,jcombination, and arrangement of parts, hereinafter more fully described, shown in the accompanying drawings, and claimed.

In the drawing, wherein like reference characters indicate corresponding parts throughout the two views:

' Figure 1 is a fragmentary top plan view showing aradiator equipped with the filling spout and closure cap constructed in accordance with the present invention, and I Figure 2 is a substantially central vertical sectional view, of the device shown inFigurev 1. i

Referring more in detail tothe drawing, 5 indicates the upper portion of theordi nary form of water radiator,-employed in the cooling systems of internal combustion engines, and this radiator has a central opening in the top wall thereof, into which is threaded the lower end of a cylindrical filling spout 6. The filling spout 6 preferably consists of a tube having the ends thereof'open and provided with an external annular flange 7 adapted to contactwith the uppersurface of the top wall ofthe' radiatorv for limiting movement of the same into the opening of, 7 1

thedevioe is applied to the radiator when thelatter.

Threadedonto the upper end of a fillinga tube 6 is a screwfcap 8 that is internally 1 threaded and has its topwall provided with T numerous relatively large perforations or v openings9 through which the steam and excessive heat may passto the atmosphere from the radiator.

Arranged centrally or spout 6 is a damper 10 mounted upon a positesides of the filling tube and has a knob or handle 12 upon one end 'thereof for facilitating manual adjustment of said damper. i

within the fining alt transverse shaft 11 that is journalled in 015- I The position of the damper will control l the amount of ste-am or heat allowed to es- 7 cape from the radiator and its position will be governed by the particularrequirements of each case with respect tothe degree of overheating experienced and the temperature in the locality where the device is being used.

From the foregoing description,- it is believed that the construction and operation as well as the advantages ofthe invention w'ill be readily understood 'and.appreciated by those skilled in the art.

Minor changes may be made without departing from the spirit and scope of the invention as claimed.

, What I cla1m as new is:

A radiator filling spout comprising a tubular open ended body externally screw threaded at its opposite ends andprovided ad acent but upward of its lower threaded end with an annular flange forming a stop shoulder, the lower threaded end being adapted to be tapped into an opening'in the radiator, and the flange being adapted to abut the latter, a perforated and screw threaded cap screwed onto the upper threaded end of said body, a shaft disposed transversely across the body at a point between opposite side Wall of the body, and a circulaidamper carried by the intermediate portion of the said shaft and disposed in the body. I

In testimony whereof I aflix my signature.
